Abstract (en)
There is provided a radar antenna module comprising one or more cavity slotted waveguide antenna arrays for radiating electromagnetic waves and one or more cavity slotted-waveguide antenna arrays for receiving electromagnetic waves is provided. A cavity slotted-waveguide antenna array is also provided. The antenna array has several waveguide columns disposed in parallel in a predetermined adjacent position with respect to one another in a housing. The housing has a front side and a rear side with several of the waveguide columns being provided with a plurality of cavity slots on the front side of the housing. The housing comprises a front part secured to a rear part, with a rear portion of the waveguide columns being formed in the rear part, and with a front portion of the waveguide columns being formed in said front part. The waveguide columns may be waveguides with a rectangular cross-section, with each or at least part of the columns being defined by two opposing wide inner surfaces, a narrow inner back surface, and a narrow inner front surface, with the plurality of cavity slots extending from the front side of the housing to said narrow inner front surface. A signal probe may be operably disposed in each or at least part of the columns for emitting and/or receiving an electromagnetic signal. A number of conductive parallel plate blinds may be conductively secured to the front side of the housing and arranged substantially perpendicular to the longitudinal direction of the waveguide columns. The rear part may be formed by a first one-piece metal element and the front part may be formed by a second one-piece metal element. A method of manufacturing an array of slotted cavity columns for use in a planar cavity slotted-waveguide antenna array is also provided.
